Automated temporary structure safety planning using building information modeling (BIM)
MetadataShow full item record
Construction safety is greatly impacted by temporary structures, such as scaffolding, formwork, and shoring. However, temporary structures are often in-stalled and utilized in many construction projects without sufficient analysis about potential safety hazards associated with the temporary structures. As a result, there are widespread safety, productivity, constructability, and site coordination problems caused by temporary structures. Focusing on scaffolding, this research proposes a method to integrate temporary structure objects into automated safety planning and optimization using Building Information Modeling (BIM). Automation algorithms for scaffolding placement, safety simulation, and optimization were created. Optimization engine generates multiple alternative scaffolding plans and the safety simulation engine simulates daily construction site conditions for quantitative evaluation of each scaffolding plan. In case studies using real world construction projects, the overall results demonstrate that the proposed approach can assist in the creation of safer construction plan by automatically evaluating and transforming a temporary structure plan into an optimized plan with lower safety risks.
